    Early Detection of Heat Recovery Steam Generator Tube Leaks

    A NACE International paper, HRSG Tube Failures: Prediction, Diagnosis and Corrective Actions highlights the challenge of these failures: Many HRSGs were originally designed for base load operation. Recent economic factors have led to drastically increased cycling of many units. This has exacerbated the rate of failures. These leaks can lead to forced outages that create associated costs including fines, lost time...

    Prevent Valve Delamination in Conventional Power Plants

    Author: Paolo Tomaini Conventional power plants are being disrupted by an increasing demand for renewable energy. The priority in providing energy to the grid associated with the intermittent intrinsic nature of the renewable energy output is creating a shift from base-load power down to cycling in traditional plants and causing failures. The demand for renewables is only expected to grow over the next few decades...
